Korg PS-3100

The KORG PS-3100 is a fully polyphonic synthesizer; this means that it has a
complete signal path for each one of its 48 keys. Each of the signal paths
roughly corresponds to a complete KORG MS-10, and of course there are diverse
functionalities on top of that which affect the output as a whole. The signal
paths are pre-patched internally, but can be overruled by patch cables as
needed. For some details, the wheel on the left for example, this is necessary
since it isn't attached to any of the internal signal paths.

Full polyphony has immense advantages, of course... you'll never grit your
teeth because the synth terminates a soft diminishing sound apruptly to start
another one. On the other hand, it has its drawbacks... heavy ones. This
thing weighs around 60 lbs and is extremely unwieldy.
